COOKING-STOVE.

Specification of Letters Patent No. 20,783, dated June 29, 1858.

1 '0 all whom it may concern:

Be it known that I, SILAs T. SAVAGE, of the city of Albany, State of NewYork, have invented a new and useful Improvement in the Construction ofCooking-Stoves Intended to be Heated by Bituminous Coal; and I declarethe following specification, with the drawings hereto annexed as part ofthe same, to be a full and perfect description thereof.

Figure 1 represents in profile an elevated oven stove with the righthand side plates removed from the oven and that part of the stove (fromA to B) which lies underneath the oven, in order to show my improvement.Fig. 2 represents in perspective that part of the stove itself from A toB, represented in profile section in Fig. 1.

Similar letters in both figures denote the same parts of the apparatus.

The object of my invention is to permit the use of bituminous coal toeffect the heating of the oven, without the consequence of fouling theflue, surrounding it, with the fuliginous matter passing over in thesmoke of that kind of coal.

In the drawing the oven A is represented in the usual form surroundedwith the hollow chamber or flue B, B, and standing on the top plate ofthe stove. In the usual arrangement the flame and smoke pass through anopening in that top plate directly into the fines B, B. WVhen usinganthracite coal no soot can form within the fiues, and even when wood isemployed as fuel if it be in good condition soot will accumulate slowlyin the fines; but when bituminous coal is used soot gathers with greatrapidity chok ing the flue, and injuring by its coating the conductingpower of the walls of the oven. In fact so great is this clogging withsoot as to make the use of said coal almost an impossibility with ovenstoves. To enable me to obviate this evil, I dispense with the currentof flame, &c., through the oven by employing the following apparatus.Within the space C, C, C, O, occupied by the oven upon the stove, tubest, t, t, are inserted ex tending between the upper and lower plates ofthe stove, and opening at the top into the oven flue, and at the bottominto the open air. It is manifest that the air which enters into thetubes t, t, t, will be heated by the flame passing through the stove;ascend into the fiues B, B, and circulate around the oven. The flue Bcan be closed at E, by a partition and an opening fitted with a registermade in the outer wall of the oven at G for the exit of the hot air; oran opening made in the top of the flue, with both sides of the flue leftfree for the air to pass up on both sides of the oven will accomplishthe same purpose.

The operation of my improvement is the communication of the heat fromthe fuel to a current of air, which shall transmit it to the walls ofthe oven free from fuliginous matter.

I do not claim the employment of hot-air to heat an oven, but

I claim:

The arrangement of air tubes across the main flue of a cooking stove,for the purpose of receiving and transmitting the caloric of the fuel,to the walls of an oven by a current of heated air, substantially as setforth in the Within specification.
